Definitions

  • the invention relates to a valve with a membrane which has an edge which is arranged in a chamber formed by a housing part and a hood.
  • Diaphragm valves can be used to meter different fluids, for example gases, vapors or liquids.
  • diaphragm valves can be used to meter or distribute highly viscous or very strongly adhesive media. In the case of diaphragm valves, deposits and thus also contamination are effectively prevented.
  • Valves based on the membrane principle are the metering fittings with the least dead space. In addition to the very low dead space volume, membrane valves are also designed to be optimized for emptying, so that residue-free removal of the medium is possible.
  • Diaphragm valves have established themselves as the preferred fitting in sterile process technology because of their advantageous design features.
  • the membranes used form movable, sealing walls that separate two rooms with usually different media (gases, liquids) and often different pressure conditions.
  • An important quality feature of a membrane is its mobility, i.e. the ability to perform a stroke perpendicular to the clamping surface (membrane surface), which can be driven mechanically.
  • the resistance of the membrane is also important, especially when aggressive media are being conveyed.
  • the mobility and durability of a membrane essentially depends on the material from which the membrane is made.
  • the main materials used for diaphragms are elastomers, which can be reinforced with fabric inserts to achieve greater strength.
  • Diaphragms made from ethylene propylene diene rubber (EPDM) have proven themselves as elastomers.
  • Ethylene-propylene-diene rubber (EPDM) are terpolymer elastomers (rubber) and thus synthetic rubbers.
  • the material is characterized by high elasticity and good chemical resistance.
  • a diaphragm valve which consists of a housing which has an upper housing part and a lower housing part.
  • a membrane with an edge bead is clamped between the two housing parts. With the help of a screw connection located outside the edge bead, the membrane is clamped in a chamber that is formed by the upper part of the housing and the lower part of the housing.
  • An external flap-like extension is formed on the edge bead. The tab-like extension is arranged between the corresponding end faces of the upper housing part and the lower housing part.
  • the clamping area of a valve membrane is subject to special requirements. First and foremost, it is used to hold the membrane, its edge area during the Closing and in the closed position is exposed to a radially inwardly directed train. If no additional seal is provided between the lower part and the upper part of the housing, the edge clamped between the housing parts can also take on the task of the static seal.
  • the edge bead, the chamber accommodating it and the end faces of the lower and upper part of the housing could be designed and dimensioned so that the maximum permissible compression of the edge bead would be achieved if the end faces of the Housing parts come to rest against one another.
  • this would require a great deal of effort in the manufacture of the membranes and the housing parts and possibly additional adaptation work.
  • a valve with a membrane The membrane is clamped between a housing part and a hood.
  • the membrane attached to a pressure piece is actuated via a spindle using a handwheel.
  • the membrane is equipped with a reinforcement fabric. It has a fastening bead on its edge, which is held in a chamber formed by the housing part and the valve cover.
  • diaphragm valves with a web are mainly used to convey fluids that do not contain solids.
  • the membrane valve has a flat membrane, which guarantees a long service life even with high switching cycles.
  • materials that can be used for diaphragm valves with a web are also suitable for higher pressures due to the support of the membrane with a spiral.
  • diaphragm valves with a free passage can also be used for media containing solids, since there is no web as an elevation in the pipeline and thus the risk of abrasion is significantly lower.
  • Such membrane valves without a web, which have a free passage can also be used, for example, for media with a high concentration of solids, such as occur, for example, when rock is transported away with water, for example when drilling in layers of earth.
  • Disadvantages of such valves with a free passage are the low durability of the membrane, which occurs due to the severe deformation when opening and closing.
  • such valves have a free passage, that is to say without a web protruding through the pipeline there is less variety in the choice of materials.
  • such valves have a poorer pressure resistance due to the insufficient support of the membrane.
  • the object of the invention is to provide a diaphragm valve which has the lowest possible abrasion even when pumping media containing solids.
  • the valve should be characterized by the lowest possible load on the diaphragm valve during operation, so that the diaphragm is characterized by a relatively long service life.
  • reliable sealing of the valve should be ensured so that no medium escapes.
  • the valve should be characterized by low flow losses or pressure losses during delivery and thus by high performance.
  • the membrane valve should be as inexpensive as possible to produce and ensure flexible use in different applications.
  • the chamber in which the membrane is arranged and / or the edge of the membrane is arched.
  • the diaphragm is clamped between a housing part and a hood in a space which is formed in a horizontal plane.
  • the chambering of the valve according to the invention is curved and is not located in a horizontal plane, but is curved downwards.
  • the valve according to the invention has a curved area in which the diaphragm rests. This bend enables a relatively free passage and at the same time a large diaphragm stroke. Furthermore, a reliable sealing of the valve is ensured by the chambering and the membrane has sufficient support.
  • the hood has a circumferential elevation that is arched.
  • the elevation is a downwardly protruding projection which preferably forms a side wall for the chambering of the membrane. The edge of the membrane can be pulled over this elevation. As a result, the circumferential elevation protrudes into a cavity enclosed by the membrane.
  • the elevation is oval around the circumference.
  • the edge of the membrane is curved. While in conventional chambered membranes the membranes have a bead or edge that lies on a plane, the membrane valve according to the invention has a membrane whose edge is curved. According to the invention, the curvature in the area of the membrane web or the membrane weir has its lowest point and then rises on both sides, so that the edge of the membrane has the highest elevation in the entry area, then steadily decreases up to the valve seat or the web or the weir and then increases again towards the exit and then increases again to the same height.

  • the curvature of the end face 23 of the edge 7 of the membrane 2 thus runs parallel to the direction of flow.
  • the membrane 2 is designed in such a way that, in the closed position, there is the lowest tension in the material of the membrane 2. When the valve opens, the membrane 2 is deformed and the tension in the membrane material increases.
